Abstract Scope |
The role of interfaces in precipitation kinetics is central because phase transformations require the formation and migration of interfaces, which are activated by chemical reactions and atomic diffusion, but also influenced at different levels by capillarity forces. Based on a new theory of nucleation and coarsening, the impacts of interfacial mobility and interfacial energy will be discussed to explain how multicomponent needle-shaped precipitates can nucleate in a matrix despite the important capillarity forces. Mathematical modelling of the entire precipitation sequence in an Al-Mg-Si system will be presented and a particular emphasis will be placed on the ageing temperature's influence. |
